Irodov Problem 3.42







As shown in the figure the two infinitely long wires are perpendicular to the screen (coming out of the screen). For , the distances of the positive and negative wires from X are given by and respectively.

We know that the electric field due to a single long wire at a distance d acts radially outwards and is given by,



Hence the total electric field for two wires is given by,



The direction of the electric field being radially outwards.

The electric potential can now evalauted as,

    In calculation of Electric field here, we have calculated only the radial component but 2nd component is missing.
    Although we have found true value of potential with help of Electric field as we have brought the particle from infinity to that point moving radially only.
